To all whom it may concern Be it known that I,-JoHN L. BEENE, a'

citizen of the United States, residing at Centrahoma, in the county ofCoal and State of Oklahoma, have invented certain new and useful-Improvements in Cultivator Attachments, of which the following is aspecification, reference being had to the accompanying drawin s.

This invention re ates to new and useful improvements in cultivatorattachments and more particularly to an attachment for thinning cottonand my object is to provide a device of this character which is soapplied to the beam or stock of acultivator as to be securely heldthereto and at the same time A further object of the invention residesin providing an arm formed in sections, one

section of whichis formed of spring steel to permit a disk carried onthe end of the opposite section to readily ride over obstructions met inthe path thereof.

Still another object of the invention re-- sides in providing a diskhaving offset portions provided on the periphery thereof, which offsetportions extend radially of the center of thedisk, and a still furtherobjectresides in providing means for adjustably securing the disk on theone section of the.

arm above referred to.

A still further object of the invention resides in providing a devicewhich is extremely simple in construction, inexpensive to manufactureand one which is efficient and useful in operation.

With these and other'objects in view, the invention consists in thenovel features of construction, combination and arrangement of parts aswill be hereinafter referred to and more particularly pointed out in thespecification and claim.

In the accompanying part of this ap lication, spective view s owing myimproved device applied to the beam of a cultivator and Fig. 2 is avertical section through the disk and attaching means therefor.

In describing my invention, I shall refer to the drawing, in'whichsimilar reference characters designate correspondin parts through theseveral views, and in wh1ch 1 indicates a cultivator beam which hasFigure 1 is a per resting thereacross, an arm 2 formed of spring metal,the one half of from said culhead 8 thereon,

drawing forming a j tivator beam, and in'order to secure the arm to thebeam,

a U-bolt 3 is provided, which receives therethrough said beam and thearm. A clamping plate 4 which is passed over the free ends of the U-boltcontacts with the arm 2 and is held in secure engagement therewith bybeing clamped. down through the medium of thenuts 5 engaged with thethreaded ends of said member 3.

The free end of the arm 2 at the lower bent end thereof is slotted asshown at 6 and an additional arm section 7 which is compoundly curvedhas the one end thereof secured to the slotted end of the arm 2 by meansof a bolt 8', the referred to end of the arm section 7 being alsoslotted whereby it will be appreciated that the member 7' .is

adjustable with respect to the arm 2. The

opposite end of the arm section 7 has a spheroidal head member 8 formedthereon through which extends a bore 9, which tapers toward one endthereof and disposed through said bore is a bolt or the like 10 formingan axis for the disk 11. Secured to the inner face of the disk 11 is asleevelike bearing 12, which has extending therethrough the bolt 10,said bolt being retained to the disk by having the head thereof disposedat the inner end of the hearing. A nut 13 is engaged with the, bolt 10between the head 8 and the outer end of the bearing 12, and anadditional nut 14 is engaged with the free end of the while arcuatelydesigned washers 15 are provided between said nuts and the head 8 forobvious purposes. From this construction, it will be seen that the disk11 will be securely mounted on the free end of the arm 7 and at the sametime it is capable of adjustment laterally with respect thereto.

The disk 11 is of the usual type used on cultivators and the like and ithas the peripherv thereof provided with offsets 16 which continue onthedisk toward the axial center thereof, thereby providing substantialradial offsets thereon. These offsets in the disk Wlll, of course, aidthe agriculturalists in spacing the products planted in drills.

From the foregoing, it will be seen that I have provided a simple andinexpensive de vice which is capable of being adjusted in various wayswith respect to the cultivator beam, and which will be very efficientand useful in operation.

which are bolt 10 to retain the While I have particularly described theelements most well adapted to perform the functions set forth, it isobvious that various changes in form, proportions and in the minordetails ofconstruction may be resorted to without de arting from the sirit or sacrificing any 0 the principles 0 the invention.

Having thus described this invention, What I claim is A cultivatorattachment comprising a curved spring arm provided with an angular headat one end thereof, said head being provided with a transverselyextending opening tapering toward one end of the oser i0 same, a disk, abolt on which said disk is revolubly mounted and having the threadedportion thereof extended through the opening in said head, Washerscarried on said bolt on opposite sides of said head, and means engagedwith the threaded end of said bolt to retain the same in revolubleposition on the head.

0 In testimony whereof I hereunto afiix my signature in the presence oftwo Witnesses.
